How can a married university student with a child serve Islam and fulfill her obligations to it in practical and effective ways?

Working for the sake of religion is the responsibility of every Muslim, and whoever turns away from it, Allah will replace them with others. The fields of work are numerous, including a person's steadfastness in obeying Allah's command, for he is the best caller [to Islam], even if he does not speak. Another field is a wife's excellent treatment of her husband, for "the good devotion of one of you to her husband, her seeking his pleasure, and her following his approval is equivalent to all of that." Another is raising children Islamically so that they may be righteous building blocks. A woman can also actively engage in da'wah among women by delivering sermons and lessons, or by utilizing computers to print and disseminate da'wah pamphlets, or by building an audio library of Islamic tapes. One must begin by inviting family, relatives, and neighbors, and cooperating with righteous women, while being keen on purifying the soul and seeking sacred knowledge.
